Tohaina
Kua tāruatia ki te papatopenga
v\sqrt{7}=5-23
Tangohia te 23 mai i ngā taha e rua.
v\sqrt{7}=-18
Tangohia te 23 i te 5, ka -18.
\sqrt{7}v=-18
He hanga arowhānui tō te whārite.
\frac{\sqrt{7}v}{\sqrt{7}}=-\frac{18}{\sqrt{7}}
Whakawehea ngā taha e rua ki te \sqrt{7}.
v=-\frac{18}{\sqrt{7}}
Mā te whakawehe ki te \sqrt{7} ka wetekia te whakareanga ki te \sqrt{7}.
v=-\frac{18\sqrt{7}}{7}
Whakawehe -18 ki te \sqrt{7}.
